FIXING CLAMP

Abstract: A clamp having an U-shaped clamp body (1) which engages a profile such as a rectangular or square pipe (2) on three sides (3, 4, 5), while the fourth side (6) of the profile is engaged by a bolt (7) which is secured by a nut (8) and extends through conical holes (9, 10) in the free legs of the clamp body (1). Conical washers (11, 12) on the bolt (7) engage the conical holes (9, 10) on the far side from the pipe (2), meaning that the bolt (7) is located somewhat eccentrically in the holes (9, 10). Tightening the bolt (7) by means of the nut (8) makes the clamp body (1) squeeze the top side (3) and bottom side (4) of the pipe (2). The conical washers (11, 12) in the conical holes (9, 10) make the bolt (7) squeeze the pipe (2) in the direction of the back side (5) of the pipe. The pipe (2) is thus squeezed from all sides, giving a strong and stable clamp connection.

Description: FIXING CLAMP The invention relates to a clamp for attaching objects to pipes and other profiles. Clamps are often used for adjustable attachment of objects to pipes and other profiles. Simple clamp units normally engage only a part of the pipe or profile, and the strength of an optimal clamp connection is not achieved. More enhanced clamps tend to be more complex, often consisting of two or more parts and a number of bolts and nuts. The purpose of the invention is to eliminate these disadvantages and bring a simple and effective clamp, especially for attaching objects to square and rectangular pipes or profiles. This purpose is achieved by means of a clamp with legs engaging the pipe on three sides, a bolt that extends through openings in the free legs of the clamp, and bevel edges that force the bolt towards the pipe, for instance one of the conical surfaces, surrounding the bolt, with complementary holes. Conical washers round the bolt prove particularly advantageous. The invention will be described in the following through an example of embodiment, with reference to the accompanying drawing. A clamp body 1 engages a square pipe 2 on three sides, top side 3, bottom side 4 and back side 5, while the front side 6 is engaged by a bolt 7 which is secured by a nut 8 and extends through conical holes 9, 10 in the top and bottom parts of the clamp body 1 and through conical washers 1 1 , 1 2. The holes 9, 10 have a common centre line which is parallel to the front side 6. The distance between said centre line and the front side 6 is less than the bolt 7 radius, while the minimum diameter of holes 9, 10 exceeds the diameter of the bolt 7, which makes it possible to install the bolt 7. The conical washers 1 1 , 1 2 on the bolt 7 engage the conical holes 9, 10 on the far side from the pipe 2, meaning that the bolt 7 is located eccentrically in the holes 9, 10. Tightening the bolt 7 makes the clamp body 1 squeeze the top side 3 and bottom side 4 of the pipe 2. The conical washers 1 1 , 1 2 in the conical holes 9, 10 force the bolt 7 in the direction of the back side 5 of the pipe 2. Thus the pipe 2 is squeezed from all sides, giving a strong and stable clamp connection. The clamp body 1 may have support members for objects to be attached to the pipe 2, and it may have any number of bolts.

Claims: C l a i m s 1. A clamp (1) for a profile such as a rectangular or square pipe (2), consisting of - a clamp body (1) engaging the pipe (2) on three sides (3, 4, 5) - a bolt (7) extending through holes (9, 10) in the free legs of the clamp body (1), - and inclined surfaces (9, 10) that force the bolt towards the pipe. 2. A clamp according to claim 1, c h a ra cte r i zed in the bolt (7) being surrounded by inclined surfaces and extending through complementary holes (9, 10). 3, A clamp according to claims 1 or 2, c h a ra c te r i z e d in conical washers (11, 12) surrounding the bolt (7).
